5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
culture is usually sustained on gel media, in much the same manner as bacteria are grown. Sufficient media consist of agar and the usual mix of macronutrients and micronutrients for the given cell type. For plant cells, enrichment with nitrogen, phosphorus, and potassium is especially important. Water is provided as a constituent part of the gel media.
Uses
A plant cell callus consists of somat
2.3. 유용생리활성단백질을 대량생산하는 방법
일반적으로 재조합 DNA를 숙주에 삽입하는 방식으로 유용생리활성단백질을 생산할 수 있다. DNA cloning은 숙주의 빠른 번식력과 Plasmid 자체의 복제 능력에 기인해 진행된다. 재조합 DNA는 원하는 DNA를 제한효소(restrict enzyme)로 추출해 DNA의 복제와 발현에
Lipopolysaccharides (LPS), also known as lipoglycans,
are large molecules consisting of a lipid and a polysaccharide
joined by a covalent bond; they are found in the outer
membrane of Gram-negative bacteria, act as endotoxins and
elicit strong immune responses in animals.
LPS is the major component of the outer membrane of
Gram-negative bacteria, contributing greatly to the structu
1. 불멸화 세포주의 가치
1.1. 기존 단백질 생산의 단점
어떤 상품이 업그레이드가 되었다면 그 전의 것에 단점이 있었기 때문일 것이다. 불멸화 세포주도 그러한 것의 일종이다. 업그레이드라는 말이 언어적으로 딱 들어맞는 말인지는 모른다. 하지만 정상적인 세포가 불멸화 세포주가 됨으로서 얻
